Digital Optical Transceiver (like SDI extend over fiber) has been widely used in the domestic and international projects. Highway, traffic, police, monitoring, security, industrial automation, power, customs, water, banking and other field’s video, audio, data, Ethernet, Phone Digital Optical began universal application. The explosive growth was due to the increase in residential quarters, water conservancy, power plants, mining, large-scale construction of the Optical civilian market, the huge potential for development in the future. Highways, urban transport and monitoring of ITS (Intelligent Transportation) market is still the largest market, but the development of the peak has passed, the future will show a steady development
Highway, traffic, police, monitoring, security, industrial automation, power, Customs, water, banking and other fields, video, image, audio, data, Ethernet optical transceiver generally begin a large number of applications. Digital Optical Transceiver (like SDI extend over fiber) main application areas are as follows:
	Intelligent building control systems
